One way to blend them is through a time - travel plot. Bruce Banner somehow travels back in time to the era of the Marauders in the Harry Potter universe. He meets young Sirius Black or Remus Lupin. Banner's knowledge of science and his modern - day thinking could be fascinating to them. The slash could develop as a strong friendship that has undertones of more. For example, Banner and Lupin could support each other in dealing with their respective 'inner beasts' - the Hulk for Banner and the werewolf for Lupin.
A simple way is to have Bruce Banner be a Muggleborn in the Harry Potter world. This would allow for his character to be integrated into the story more easily. The slash aspect could involve a relationship with Harry Potter himself. They could bond over their shared experiences of feeling different from others. Harry as a wizard with a unique past and Banner as a scientist with a big secret (the Hulk).
To blend them well, consider their personalities. Harry is brave and determined, while Banner is intelligent and somewhat reserved. In a fanfiction, they could meet during a dangerous situation, like a dark wizard attack on a Muggle area. Banner might accidentally get involved and use his scientific skills to help, which catches Harry's attention. As for the slash part, their growing respect for each other could turn into a deeper emotional connection as they continue to face challenges together and learn more about each other's worlds.
One interesting concept could be a crossover where the magic of the Harry Potter world interacts with Bruce Banner's scientific knowledge. Maybe Banner could be intrigued by the potions in the wizarding world and try to analyze them with his scientific mind. Another concept might be a situation where the Hulk's strength is pitted against the powerful magic spells of Harry Potter characters.
Perhaps Bruce Banner adopts Harry Potter after the events at Hogwarts. He takes Harry to the world of science, showing him things like advanced laboratories and scientific research. Harry, in turn, shows Bruce the wonders of magic. Their bond grows as they learn from each other, and together they face new threats that combine elements of both the magical and scientific worlds.
I really liked a fanfic where fem Harry Potter accidentally travels to Bruce Banner's world. It shows how she tries to adapt to this new world full of science and technology, which is so different from the magical world she's used to. And Bruce Banner is intrigued by her magic. It's a great exploration of two very different characters coming together.
In fanfiction, Bruce Banner could save Harry Potter through his scientific knowledge as well as the Hulk's powers. Maybe there's a situation where a magical curse is spreading uncontrollably. Bruce, in his normal state, could analyze the curse using his scientific expertise and figure out a way to stop it. And if there are any physical manifestations of the curse that need to be dealt with, the Hulk could step in and use his strength to destroy or contain them. This would show a great combination of the scientific and magical elements in the story.
A good way is to focus on their shared traits. Both Harry and Daryl are survivors. Harry has survived Voldemort's attacks and Daryl has survived the zombie apocalypse. So, in fanfiction, they can bond over their experiences of facing tough odds. For instance, they could exchange stories of loss and how they overcame it.
Well, you can start by finding common traits. Both are young leaders in their own ways. Harry leads his friends at Hogwarts in their battles against Voldemort, and Ciel leads his servants in his fight against those who wronged him. So, a story could be built around them sharing leadership strategies.
One idea could be that Bruce Banner is somehow transported to the wizarding world of Harry Potter. Maybe he arrives during a time of great danger, like when Voldemort is at his most powerful. Bruce's scientific knowledge could be combined with magic in unexpected ways. For example, his understanding of gamma radiation might interact with some of the more dangerous magical spells or potions. He could also form an unlikely friendship with Harry Potter. Harry could teach him about magic, while Bruce could show Harry some of the scientific concepts from his world.
If they meet, Bruce Banner might be really intrigued by the magic in Harry's world. He could see it as a new form of science. And Harry could be fascinated by Bruce's scientific knowledge. They might exchange ideas, with Harry showing Bruce how magic can do things like teleportation, and Bruce explaining some scientific concepts to Harry, like how gamma radiation works.
Harry is brave and determined. Bruce is intelligent but often hesitant due to his fear of the Hulk. Harry might encourage Bruce to be more confident. He could say things like 'You have so much power within you, don't be afraid to use it for good.'
Well, perhaps Harry would be exposed to a whole new world of science. Bruce Banner could use his scientific knowledge to help Harry better understand magic in a more logical way. Maybe he'd try to find a scientific explanation for magic. And Harry could also introduce Bruce to the magical world, which would be quite an adventure for Bruce.
